Hi. I upgraded from an Alti-2 Galaxy to an Ares II a few weeks ago, after evaluating both the Ares II and the Viso+. The Ares II has a larger screen and a low profile. The Viso's screen is fine but I felt that the Ares II had overall better construction and it works better for my use case -- I abuse gear and needed something with the flattest possible profile. As far as the internals and firmware, both appear to use the Bosch barometric sensor and have similar capabilities. Cheers, pr3d Does Ares II feel "heavy" on your palm (as compared to Viso)? . Have the Ares II for about 50 jumps now. I went from analog to digital with it. Great altimeter and being 'the new kid on the block', it gets a quite bit of attention on the ride up to jump altitude. The positive comments I gotten so far are typically about the clarity and viewing angle of its LCD. It is (obviously) heavier that the Viso but I doubt one will notice it. I wear it on my forearm rather than around my wrist (like how I did with my analog).
